Your the man!
gcc4 and -fno-tree-ch did the trick for me, too.
-fno-tree-ch was mentioned earlyer on this list, to compile with gcc4
on OS X. But since gcc4 is still not in the default toolchain, I did
not even try :(.
Seams that we have a problem with gcc3.3 and not gcc4 for once :)
The error behavement is similar on your machine. I also got bus error
(Sometimes it did not reach the menu, too. I started to hit the 3
very early, so I could go right thru it... Early crashes always
happened for me on MS-DOS 6.22 and DOS 7.
Tested it with DOS 6.22 and DOS 7 (win95). No Problems so far.
I hope Fabrice stumbles upon this.
Maybe we should make the Patch a little more selective with "ifeq ($
(CONFIG_DARWIN),yes)" and post it.
Don't know whether this affects other Platforms, too...
Thanks for Your work so far!

I just did some tests on the freedos image from your web-site and
my first
impression is that these crashes are something compiler related.
When I
build qemu with
./configure --prefix=/usr/local --cc=gcc-3.3 --target-list=i386-
softmmu --enable-cocoa
and start your image with
qemu -hda harddisk_1.img -soundhw sb16
it starts up and immediately crashes after 1 or 2 seconds (Bus
error) -
even before I could choose one of the 3 menu options. For the next
test I
applied the patch below and compiled qemu with GCC 4.0.1:
--- Makefile.target
+++ Makefile.target

ifeq ($(CONFIG_DARWIN),yes)
./configure --prefix=/usr/local --cc=gcc-4.0 --target-list=i386-

With this build everything seems to work perfectly. I boot into
option 1
and run the DOOM demo with b.bat - it runs for ca. 100 seconds and
then
quits back to DOS saying 'timed 2134 gametics in 2325 realtics'.
Can you try if using GCC 4 helps for you too? I'll do some more
tests now.
Hopefully I can track down the problem to someting more specific.

You find a freedos including doom here:
http://www.kberg.ch/q/userfiles/freedosdoom.zip
or at the oszoo.org
Crashes:
- when choosing option 1 (standard)
about 10-20 sec into doom, when playing timedemo (doom -timedemo
demo3), otherwise, too.
This used to work great before.
Thanks,
Mike
